[libvirt] [PATCH 00/14] Add support for XBZRLE migration compression

[Jiri Denemark]

QEMU supports XBZRLE compression of repeatedly transferred pages during
live migration and this series makes it usable through libvirt. The first
two patches add support for VIR_MIGRATE_COMPRESSED flag that enables
XBZRLE compression. Patches 3--9 add an enhanced and extensible version
of virDomainGetJobInfo and make various migration statistics available
through it. The rest of the patches (10--14) add APIs for querying and
changing XBZRLE compression cache size.

Jiri Denemark (14):
  Introduce VIR_MIGRATE_COMPRESSED flag
  qemu: Add support for compressed migration
  Introduce virDomainGetJobStats API
  python: Implement virDomainGetJobStats wrapper
  remote: Auto-allocate params in remoteDeserializeTypedParameters
  remote: Implement virDomainGetJobStats
  virsh: Use virDomainGetJobStats in domjobinfo if available
  qemu: Parse more fields from query-migrate QMP command
  qemu: Implement virDomainGetJobStats
  Introduce virDomainMigrate*CompressionCache APIs
  python: Implement virDomainMigrateGetCompressionCache wrapper
  remote: Implement virDomainMigrate*CompressionCache
  virsh: Add migrate-compcache command
  qemu: Implement virDomainMigrate*CompressionCache
